Field And Stator Ground Modules - GE G60 Instruction Manual

CHAPTER 3: INSTALLATION
The clock configuration LED status is as follows:
• Flashing green — loop timing mode while receiving a valid data packet
• Flashing yellow — internal mode while receiving a valid data packet
• Solid red — (switch to) internal timing mode while not receiving a valid data packet
The link/activity LED status is as follows:
• Flashing green — FPGA is receiving a valid data packet
• Solid yellow — FPGA is receiving a "yellow bit" and remains yellow for each "yellow bit"
• Solid red — FPGA is not receiving a valid packet or the packet received is invalid

3.5 Field and stator ground modules

GPM field and stator ground fault protection modules can be used with the G60. The stator ground unit, for example, works
in combination with the G60 to provide 100% stator ground fault protection during generator start-up, running, and
stopped conditions. The GPM units are set up and run from the G60. See the
Modules Quick Reference Guide
The field ground protection modules are used with the G60 in the following configurations:
• Field low voltage protection system (order code GPM-F-L) for voltages up to 600 V DC
• Field high voltage protection system (order code GPM-F-H) for voltages greater than 600 V DC
• Stator protection system (order code GPM-S)
These systems are illustrated for comparative purposes in the figure.
With GPM-S, use a CT/VT module with Sensitive Ground capability (for example 8G, 8J, 8M, 8R) to connect stator ground
protection CT (204-SD-43737) input to the G60 device.
